Clogged fuel lines?

So my Supra has been sitting for 2 years without being started. Before starting I changed the plugs, battery, put in 5 gallons of fresh gas, and put a little oil and gas mixture in the spark plug holes to lubricate. She started up just fine for about 2 seconds and then nothing. The starter was clicking but couldnt get anything. Took out plugs and added even more fuel and she started for a second but died immediately with a lot of unburnt fuel out of the exhaust. When I filled up I noticed a bit of rust around in the gas nozzle. Also the fuel gauge shows empty.

 

How can I tell if fuel is getting to engine?

Check to see if you pump still has its filter on. If so there's no way your fuel line is blocked. Or, unscrew the feed line from the fuel filter and side up the pump and see if there's fuel coming out. You do this by bridging the B+ and FPR terminals on the diagnostic port in the engine bay and turn the ignition on.

My car was sitting for 6 years and wouldn't start.... Realized the fuel lines had a leak and was gushing fuel onto the floor after a few attempts to start it. Changed out my fuel lines and started in the second try...

Fuel Pump Rusted.jpg

 

So I yanked the fuel pump and I think I have at least some of the problem. Everything was completely rusted. I can't imagine that any of the connectors could have been working which would explain the broken fuel gauge. I'm going to try and test the fuel pump to see if it still works. Can I just hook it up straight to the battery. How do I get all of the rust out of the tank? I have scrubbed most of the rust off. Is there anything I can coat it with to make sure it doesn't happen again?

Dude, put that pump in the bin. Buy yourself a new walbro, there only about £80 inc fitting kit. If it were my car, I'd drop the tank and stick a good second hand tank in there with no rust. Keron on here (Extreme performance) will be able to sort you out with all the parts required pretty cheaply too. Don't risk running that pump or using the tank, if any crap gets down to your injectors then you'll have problems. While your on, stick a new toyota fuel filter in there too.

Yeah that pump is done. Going to buy a new fuel filter and Walbro now. I hope the Walbro lives up to the stock one. The tank was recently replaced and looks pretty good outside of the debris in the tank, so I'm just going to thoroughly flush and vacuum it. Let this be a precautionary tale to those that would leave their cars unattended for too long. Thanks for everyone's help.
